Oil Sludge Treatment, project for ass covering. It is normally existbeside the rigs, or the oil production plants, a big pit, with all the oily sludge left, so solids oil water mixed together, without any function to reuse anything. Then that is where oil sludge treatment system needed. GNOST1, GNOST5, GNOST15 is so far 3 standarized model, which may hopefully meet most of the requirement.

Sludges that contain oil and water are generated through a variety of activities and processes on board ships, including sedimentation in tanks, tank dewatering processes, and leaks or cleaning cycles in backflush filters and separators for treating fuel oil and lube oil. The trend for combusting high density fuel oils of higher viscosity, as well as the use of residues as a fuel for medium­speed diesel engines, also increases the production of sludge from both fuel oil and lube oil.Emergence of sludges containing oil and water The build up of these oil and water­containing sludges represents a considerable disposal problem.

Though many options can be implied, GN utilize the standard separation equipment to do the work, which also make sense, it is for separation, the key equipment would be decanter centrifuge, shakers, plus disc stac separators. GN Oil Sludge Treatment System is to use chemical to wash the oil sludge with heat to temperature of 60-70 C degree. After washing the slurry is pumped to GN separation equipment to separate into oil, water and solids. The recycled water can be reused in the washing process, and the oil is clean enough to sell to the refinery company, the solids contain oil between 2%-5% which can be sent to biodegradation or thermal unit for final disposal.
